DIG-BY ESMOND COOK, OF SYDNEY, NEW SOUTH WALES, AUSTRALIA.

VENTILATION DEVICE FOR BOOTS AND OTHER FOOTWEAR.

Application filed August 23, 1915.

To all whom it may concern:

Be it known that I, DIGBY ESMOND Coon, a subject of the King of GreatBritain, residing at Sydney, in the State of New South Wales,Commonwealth of Australia, have invented certain new and usefulImprovements in Ventilation Devices for Boots and other Footwear, ofwhich the following is a specification.

This invention relates to improvements in ventilation devices for bootsand other foot wear, my object being to provide a device which willpermit the ingress or egress of air but prevent the passage therethroughof water or dust.

The invention consists essentially in the employment across theventilation opening of fine wire gauze the inner and outer surfaces ofwhich are protected by flanges, projections, perforated or skeletoncovers or caps or the like, whereby other materials such as portions ofthe clothing are prevented from being brought into direct contact withthe gauze.

A device of this character will permit the free passage of air into thefootwear. Preferably however I provide two or more parallel pieces offine wire gauze maintained relatively to each other permanently bydistance pieces or otherwise rigidly held apart. For example, I find avery useful ventilation device is formed by fixing two fine wire gauzedisks in a short light metal tube or cylindrical member a short distancefrom each end and keeping them apart say th to ith of an inch by adistance ring. A hole is made in the leather or other material and thetubular shaped device inserted and retained in position, preferably by alocking member.

The ventilation opening may be of any desired shape and size providedmeans are taken to prevent contact of other material with the surfacesof the gauze or the outer surfaces when parallel pieces are used.

I will now refer to the sheet of drawings herewith in which isillustrated the preferred form of device applied to a boot.

Figure 1 is a partial perspective view illustrating the device securedin position. Fig. 2 is an enlarged perspective view, and, Fig. 3 asimilar view with locking member separated. Fig. 4 is a cross section.

Specification of Letters Patent.

Serial No. 46,963.

The same reference numerals indicate the same or like parts.

5 is a boot through an opening in which, preferably at the instep, ispassed the member 6 which issecured in position by the locking member 7.The member 6 consists of two gauze disks 8 maintained apart by means ofthe ring 9 and has the flange 14. These disks are held in a groove orrecess 10 in the member 6 which is threaded at 11. The locking member 7is also threaded at 12 and takes over the threaded portion 11 and holdsthe ventilating device securely in posltion.

13 are holes in which are inserted the prongs of a tightening tool.

Having thus described my invention What I claim as new and desire toprotect by Letters Patent, is

l. A ventilation device for boots and other footwear consisting of anannular locking member having a securing flange and a screw-threadedopening, an annular ventilator member provided with an annular seattherein and a screw-threaded portion to engage the screw-threadedopening of the locking member, Wire gauze ventilators secured in saidanular seat of the ventilator member, and means for holding the wiregauze ventilators in spaced parallel planes.

2. A ventilation device for boots and other footwear consisting of anannular locking member having a securing flange, an annular ventilatorcarrying member separably connected to the locking member, and wiregauze ventilators secured in the said carrying member and disposed inparallel spaced planes.

3. A ventilation device for boots and other footwear consisting of anannular locking member, an annular ventilator carrying member separablyconnected to the locking member, wire gauze disks disposed in theventilator carrying member, and a ring between said disks for holdingthe latter in spaced relation.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

CHARLES E. GRAHAM, HENRY K. CLARKE.
